Fig. 1 is a side elevational view, partly in section, of a rear view mirror structure incorporating my improvements;

Fig. 2 is a perspective view of the member that receives and supports the mirror;

Fig. 3 includes enlarged fragmentary sectional details of the casing of the mirror head before its peripheral portion is formed or peened inwardly; the plastic mounting member in its original or relaxed condition, and the glass mirror, prior to the assembly of these parts, and

Fig. 4 is a similar view of the parts shown in Fig. 3 in assembled condition.

In the following detailed description of the invention and throughout the views of the drawing, like reference numerals designate like parts.

The structure shown in Fig. 1 includes a mirror head designated, generally, by the reference numeral 1. head is adjustably connected in a conventional manner through the medium of an element 2 to a supporting bracket 4.

5 designates the casing of the mirror head which is desirably made of sheet metal. It is shown as a shallow circular shell having an open side surrounded by 21 peripheral flange 6, the latter being illustrated in Fig. 3 in its original condition. The casing, however, may be made of any desired depth or configuration so long as an internal shoulder 7 1s provided between the body portion of the casing and the peripheral flange 6 thereof.

10 denotes, generally, a frame-like plastic mounting member, shown in the present instance as being in the form of an annulus. The member includes a flat web 11, a rim 12 that surrounds sides of the plane thereof plastic mounting join the inner flange 14. and to the web 11. The depth of the ribs 21 is desirably less than that of the flange 14, as best appears from Figs. 3 and 4, and the bead is preferably of about the same depth as the ribs.
